            Bug ID: 318949
           Summary: XML in message body causes KMail to hang after every
                    action
    Classification: Unclassified
           Product: kmail2
           Version: 4.10.2
          Platform: Archlinux Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: composer
          Assignee: kdepim-bugs at kde.org
          Reporter: kde.org at tjbp.net

I am often sent large quantities of XML pasted in an email, and when composing
my reply message I am faced with frequent hangs. KMail becomes completely
unresponsive, and starts to consume about 20% of my CPU time. The more XML, the
longer the hangs will last. The hang seems to be triggered when I first open
the composer to reply, and then again after 8 or so words I write.

I suspect this might have a connection to the greater-than signs used to indent
quoted text, and something attempting to parse them is getting confused by all
the greater-than signs in the XML.

Apologies if this is a duplicate or even already fixed (though I did search),
since I'm aware I'm not using the latest revision.

Reproducible: Always

Steps to Reproduce:
1. Send an email with a significant amount of XML (say ~100 elements) to
yourself.
2. Open a reply to that email.
